解决方案 »

  1.   

    这是index.jsp：
    <%@page contentType="text/html;charset=gb2312"%><%@page import ="ch08.BooksBean"%><html>
    <jsp:useBean id="BBean" class=ch08.BooksBean" scope="session"/>
    <jsp:setProperty name="BBean" property="*"/><% int booksid;
    String booksname;
    String author;
    float price;
    float discount;
    String publisher;
    String note;

    booksid=BBean.getBooksid();
    BBean.setBooksid(100);

    booksname=BBean.getBooksname();
    BBean.setBooksname("高技术开发");

    author=BBean.getAthor();
    BBean.setAthor("Gate");

    price=BBean.getPrice();
    BBean.setPrice(50);

    publisher = BBean.getPublisher();
    BBean.setPublisher("火星出版社");


    <!-- 表达式语言访问-->
    出版社:${BBean.publisher}
    <br/>

    ISBN编号:${BBean.booksid} <br/>

    价格:${BBean.getPrice()}
     %><body>成功
    </body></html>
      

  2.   

    这是javaBean：
    package ch08;public class BooksBean {

    public int booksid;

    public String booksname;

    public String author;

    public float price;

    public float discount;

    public String publisher;

    public String note;

    BooksBean(){}

    public String getAuthor(){

    return author;

    }
    public void setAuthor(String author){

    this.author=author;
    } public int getBooksid(){

    return booksid;
    }
    public void setBooksid(int booksid){

    this.booksid=booksid;
    }
    public String getBooksname(){

    return booksname;
    }
    public void setBooksname(String booksname){

    this.booksname=booksname;
    }
    public float getDiscount(){

    return discount;
    }
    public void setDiscount(float discount){

    this.discount=discount;
    }
    public String getNote(){

    return note;
    }
    public void ssetNote(String note){


    this.note=note;
    }
    public float getPrice(){

    return price;
    }
    public void setPrice(float price){

    this.price=price;
    }
    public String getPublisher(){

    return publisher;
    }
    public void setPublisher(String publisher){

    this.publisher=publisher;
    }
    }
      

  3.   

    <jsp:useBean id="BBean" class="ch08.BooksBean" scope="session"/>
    少个引号
      

  4.   

    楼上说得也是一方面！
    但最重要的是我的javaBean中
    构造函数不是public的啊！！！！！！！！！
